WebDec 24, 2024 · The lymphatic system also facilitates fatty acid absorption from the digestive system. During fat digestion, fatty acids are digested, emulsified, and converted within intestinal cells into a lipoprotein called chylomicrons. Lymph drainage vessels that line the intestine, called lacteals, absorb the chylomicrons into lymph fluid. Web(4) chylomicrons then leave intestine via lacteals (lymphatic system vessels), re-entering the bloodstream via thoracic duct a lymphatic vessel emptying into the subclavian vein at the base of the neck.

"The three stages of the chylomicron are nascent, mature, and remnant. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. These then pass from the intestinal lumen into the enterocyte, where they are re-esterified to form triglycerides. The triglycerides are then combined with phospholipids, cholesteryl esters, and apolipoprotein B48 (ApoB48) to form a nascent chylomicro… " - Chylomicrons and lacteals
